MESH MICRON CHART 

What is a micron?

         Micron is the measure of length Most frequently micron is used to describe the measure of length of tiny particle size. The term micron is actually commonly used shorthand for micrometer (American spelling) or micrometer (international spelling). The official symbol for the micrometer is μm, sometimes simplified as um. A micrometer is defined as one-millionth of a meter, a little more than one twenty-five thousandth of an inch.

What does mesh size mean?

          Mesh number and its relationship to the size of the openings in the mesh are Mesh size and thus the size of particles that can pass through these openings. Figuring out the mesh number is simple. What you have do is count the number of openings in one linear inch of screen. This count is the mesh number. A 10 mesh screen means there are ten little square openings across one inch of screen. A 50 mesh screen has 50 openings per inch, and so on.

 Note: As the number indicating the mesh size decreases, the size of the openings and thus the size of particles captured increases. Lower mesh numbers = Larger particle sizes. This  is to be very important to remember that mesh size is not a precise measurement of particle size. This is because screens can be made with different materials with different thicknesses of strands of wire. Thinner strands, larger the openings that a particle can pass through, and vice versa. Also, a mesh is 2D and the 3D shapes of particles vary dramatically. For mesh to the micron, conversion sees the Mesh Micron chart.
